Adding bursting doesn't make your IP faster, you should only add it if you need it. That code you attached doesn't look like it's going to achieve what you are looking for. You have sections in the always block that are modifying the register "bc" so if that value is decrementing for each beat of the burst and getting reloaded by the next read at the same time you will most likely have a functional failure. Instead of spending time explaining how to structure this code I suspect your IP doesn't really need to support bursting since what you appear to be trying to code looks like a counter.

Thank you very much for your reply.
The code is not the final version, it only be used to check what the maximum speed can this ip reach, so the register "bc" must have some problem, as well as the counter that returns to PC program that used only to verify the ip is working.
Actually I don't really need bursting, what I want is to make a ip has the same speed as on-chip memory, can you give me some advise? Thank you.
